Hitting this crash, I think it's trying to run clangd on my C project

Someone also ran into this and did a PR but never addressed the comments
#616

Would you want to pick it up? Not much left to do there

Sure I will take a look at it, thanks.

I opened PR #712 with commits from earlier PR and hopefully addressed the comments.

With the change Serena was able to activate and onboard my C project. 🎉
